"Open my arsecheeks, babe."
Ginny's voice was thick with lust, it had almost a husk to it. She was laying flat on her stomach, a pillow underneath to raise her bum just slightly higher than the rest of her body. Her face was to the side, a single eye watching Luna who sat to her side. "What do you have for me?" Luna asked as she placed a hand on each of Ginny's cheeks, gripped and spread them apart, revealing Ginny's anal hole. Ginny didn't reply, except from a sharp intake of breathe as she pushed outwards with her anus. "It's opening!" Luna said with delight, her eyes fixed on the hole as it twitched and began to open up. Ginny was breathing heavily, and let out a great sigh as a big fart left her arsehole. "Mmmm!" Luna voiced as she pushed her head downwards, taking the fart directly into her nose.
"So smelly." was her response as she inhaled, then gave the arsehole an affectionate lick with her little tongue. "Smell good?" Ginny asked as her next fart built up within her bowels. "Well, it's quite vile actually. But I love it nonetheless." she spoke, ending with a giggle. "Please may I have some more?" Luna asked, giving the bum cheeks a flirtatious squeeze, holding them open still. "You want more smelly farts, babe?" she asked, biting her bottom lip. A wave of pleasure washed over Luna's virgin pussy. "Please!" Luna begun, desperate. "I'm your fart whore, please fart up my nose." she begged further, and her sentence was barely over before Ginny's arsehole opened up again, releasing shit smelling air up into Luna's nostrils. Moaning with lust, she gagged from the smell, then gave the hole another lick as she swallowed the tatse.
"You have the foulest, most perfect farts, Ginny." Luna spoke, raising her head upwards to look at her lover. Ginny blushed. "I'm going to plug your stink hole with my fingers!" Luna said suddenly, and before Ginny could prepare herself for the intrusion, Ginny had effortlessly thrust two fingers into the tight hole. Her anus squeezed around the fingers and it was air tight. Ginny let out a big moan and she wriggled, but Luna held her in place with a hand on her back. "But with my stinky shit hole all plugged up, how am I supposed to fart?" Ginny asked, a hint of sadness in her voice masked over by the arousal. Luna giggled, removed her fingers so that just the tips where in, then slammed them back in down to the knuckles. Ginny thrashed in pleasure, and during the tension of it all, a fart was forced out of her.
But it didn't leave the hole. The pressure remained in Ginny's shit chute, burning slightly. "That's how." Luna said, smiling at the warmth the trapped fart caused on her fingers. "Oh, what a feeling. It's all warm in my shit tunnel." Ginny's eyes closed in pleasure at the new sensation, but the pressure was building up. "Urgh, you'll have to unplug me soon!" Ginny said, another fart building up. Luna nodded her head, then inhaled deeply. "What're you doing, silly girl?" Asked Ginny, who then moaned aloud as another fart was trapped inside. Luna kept silent as she continued to hold her breath. "Babe, my arse is getting all full up with trapped farts! It's stinging!" she was fidgeting a lot now as her tummy rumbled; she farted again.
Luna was desperate for air now. She moved her head down to Ginny's arsehole, and without warning she suddenly removed her fingers. The moment she did this, Luna was forced into inhaling deeply through lack of air, allowing the huge bursts of smelly farts to be inhaled directly into her empty lungs. Ginny watched in shock as a big group of her farts were released into Luna. After inhaling, Luna exhaled, panting heavily, her eyes watery. "Fuck Luna babe, you do the naughtiest things to me." Ginny said, sighing at the relief of having freshly emptied bowels. "I'm your fart slave, that's why. So smelly and delicious!" another wave of pleasure flushed over her, and she gave in to it. Ginny sat up opposite Luna, and facing each other with their legs spread, they rubbed their clits together, and finished their orgasms by squirting on each others pussies.
"Oh, babe. I do love you." Ginny expressed rather suddenly, as they collapsed into each others arms. The girls had been fucking each other for months, but Ginny had never said something like that before. She knew that Ginny loved her, of course, as did Hermione. "Do you love me more than you love cock?" Luna asked, her voice plain. Ginny raised her eyes to meet Luna's. "Don't make me choose." she said with a smile. Luna stared blankly. "Hermione loves me more then." was Luna's response. "That dyke is utterly obsessed with you." Gin said, rolling her eyes. "Luna, you're my fart whore. Neville and Hermione are basically your sex slaves. Neville is filled with lust, like all boys, but Hermione is hopeless for you; and me, well... I just like to fuck people." Ginny giggled, but Luna only smiled in response. She was content with their situation.
"Little slut." Luna teased, kissing Ginny on the lips once. "But I think it's about time I tried some cock myself." Ginny raised her eyebrows; she knew Luna was a virgin. Aroused, she began lightly toying her own clit. "Who do you have in mind?" she asked, and Luna closed her eyes in thought. Moments of silence passed, and as Luna thought about all the boys and men she began to toy with her clit too. "Neville first, because it'll be easy, and it won't last long since he's a pansy." Their hands increased speed and their interlocked legs began to tremble. "But I think what I really need is..." her voice trailed into a whisper. "A centaur cock." as the words left her mouth, both girls shuddered into hard orgasms, squirting their girl cum in every direction. Ginny's squirt quickly turned into piss, and Luna joined her.
